Due to an oversight while building it (forgot to put a flat on the bar that the set screw screws into), the y-axis pulley may become loose over time. If this happens, you'll need to remove the access panel on the y-axis uprights and tighten the set screw.

* Can I mill printed circuit boards on this thing? Hasn't been done yet, but should be possible. However, due to slop in the gantry, it's unlikely you'll be able to get very thin traces reliably.

* Can I drill printed circuit boards on this thing? Yes! Basically, you just need to translate your drill file to the ''lingua franca'' of the mill, [http://www.linuxcnc.org/docview/html/gcode_overview.html G code].

* How do I secure my work piece when milling? Currently, you have to simply tape it down with masking/painter's tape. Eventually, a better system will be devised. If you have ideas about what such a ''better system'' might look like, please contact [[User:Mysterious Paul|Paul Kerchen]]!

* How do I secure my work piece when milling? The base has a (removable) piece of MDF with several 1/4-20 blind nut inserts embedded in it. Using 1/4-20 bolts and fender washers, you can secure your work piece fairly well.

Maintenance Info

There is no routine maintenance required. When you're done with it, be sure to power down the controller box AND the linux box (it doesn't automatically power down on shutdown).

Due to an oversight while building it (forgot to put a flat on the bar that the set screw screws into), the y-axis pulley may become loose over time. If this happens, you'll need to remove the access panel on the y-axis uprights and tighten the set screw.
